Android應用程序可以在模擬器中正常運行，但不能在真實設備中運行？

Question

我正在制作一個簡單的Music Player應用程序。 它已經可以在我的模擬器上完美運行，但是在將其安裝到設備上后，它顯示“應用程序MusicShare （進程com.example.musicshare）意外停止。請重試” 。

我的設備是Galaxy S2，我從bin文件夾中獲取了apk。 我嘗試使用“不帶未簽名密鑰的導出文件，而無法安裝它。這是清單 ：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.musicshare"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".AndroidBuildingMusicPlayerActivity"
            android:label="@string/app_name"
            android:configChanges="keyboardHidden|orientation">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name=".PlayListActivity" />
    </application>

</manifest>

任何幫助將不勝感激。 謝謝！

這是我在設備上調試之后從logcat發出的錯誤日志：

Answer 1

@Pleerock是正確的。 顯然這是路徑問題。 它應該是“ / sdcard / media / audio / Music /”。 謝謝您的幫助。

Answer 2

有時您需要導出整個項目並獲取.apk文件並進行安裝
